I have the same issue. @LovelyYanki have you been able to solve it so far?

[hamishmack]

The pkg-config package 'webkit-1.0' version >=1.8 is required but it could not be found.

This normally means the required C libraries and header files have not been install.

On ubuntu you need to run sudo apt-get install libwebkitgtk-dev or for the webkitgtk3 cabal package first run sudo apt-get install libwebkitgtk-3.0-dev.

[erikkaplun]

any help on OS X though? it seems non-trivial to install Webkit on OS X — are there libraries to just "bind" it to e.g. Safari?

[hamishmack]

Here is how I currently install webkitgtk on OS X. Safari is not webkitgtk based so I don't think you can bind to it.

[erikkaplun]

oh, thanks, that's very useful — hopefully it'll work nicely in an environment where Homebrew is normally used.

[erikkaplun]

Turns out the problem with the MacPorts based installation is that the webkit-gtk3 port there depends on a newer version of libiconv, which, if installed, will cause the rest of my Haskell project to fail to build. So I found myself in a constant need to port -f deactivate and port activate the port.

Then, I discovered that webkitgtk has appeared in Homebrew just some hours ago. So I installed it.

After realizing that it lacks a .pc file, I manually added one, according to what I saw in MacPorts and the webkitgtk-2.10.4 source tarball. So now I have:

$ cat /usr/local/lib/pkgconfig/webkitgtk-3.0.pc 
prefix=/usr/local/Cellar/webkitgtk/2.10.4
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include

Name: WebKit
Description: Web content engine for GTK+
Version: 2.10.4
Requires: glib-2.0 gtk+-3.0 libsoup-2.4 javascriptcoregtk-4.0
Libs: -L${libdir} -lwebkitgtk-3.0
Cflags: -I${includedir}/webkitgtk-3.0

also, pkg-config seems to find webkitgtk-3.0 just like it did with the MacPorts installed one:

$ pkg-config --cflags webkitgtk-3.0
-D_REENTRANT -I/usr/local/Cellar/webkitgtk/2.10.4/include/webkitgtk-3.0 -I/usr/local/Cellar/gtk+3/3.18.6/include/gtk-3.0 -I/usr/local/Cellar/glib/2.46.2/include/gio-unix-2.0/ -I/usr/local/Cellar/cairo/1.14.4/include/cairo -I/usr/local/Cellar/libepoxy/1.3.1/include -I/usr/local/Cellar/pango/1.38.1/include/pango-1.0 -I/usr/local/Cellar/harfbuzz/1.1.2/include/harfbuzz -I/usr/local/Cellar/pango/1.38.1/include/pango-1.0 -I/usr/local/Cellar/atk/2.18.0/include/atk-1.0 -I/usr/local/Cellar/cairo/1.14.4/include/cairo -I/usr/local/Cellar/pixman/0.32.8/include/pixman-1 -I/usr/local/Cellar/fontconfig/2.11.1/include -I/usr/local/Cellar/freetype/2.5.3_1/include/freetype2 -I/usr/local/Cellar/freetype/2.6_1/include/freetype2 -I/usr/local/Cellar/libpng/1.6.19/include/libpng16 -I/usr/local/Cellar/gdk-pixbuf/2.32.2/include/gdk-pixbuf-2.0 -I/usr/local/Cellar/libpng/1.6.19/include/libpng16 -I/usr/local/Cellar/libsoup/2.52.2/include/libsoup-2.4 -I/usr/local/Cellar/webkitgtk/2.10.4/include/webkitgtk-4.0 -I/usr/local/Cellar/glib/2.46.2/include/glib-2.0 -I/usr/local/Cellar/glib/2.46.2/lib/glib-2.0/include -I/usr/local/opt/gettext/include -I/usr/include/libxml2

however, when building my project, which depends on the webkitgtk3 Cabal package, I get:

    setup: Missing dependency on a foreign library:
    * Missing C library: webkitgtk-3.0
    This problem can usually be solved by installing the system package that
    provides this library (you may need the "-dev" version). If the library is
    already installed but in a non-standard location then you can use the flags
    --extra-include-dirs= and --extra-lib-dirs= to specify where it is.

Any ideas whatsoever? Does the homebrew formula actually not build a suitable webkitgtk-3.0 library? It appears the versions in the 2.10.4 Homebrew formula are newer than the in the 2.4.9 MacPorts port — might that make a difference?

[erikkaplun]

OK, so turns out the webkitgtk-3.0.pc file I placed there needed to be updated to contain this instead:

...
Libs: -L${libdir} -lwebkit2gtk-4.0
Cflags: -I${includedir}/webkitgtk-4.0

...which is according to the webkitgtk*.pc.in file in the webkitgtk source tarball. However — I now get this:

— and on closer inspection, it's true htat webkit/webkitdom.h is not found because there's only this one:

/usr/local/Cellar/webkitgtk/2.10.4/include/webkitgtk-4.0/webkitdom/webkitdom.h

Again, any ideas? If we could fix this, webkitgtk3 be installed on OS X without any ugly package hackery.

[erikkaplun]

If I symlink the webkitdom directory to webkit, the webkitdom.h file is found, but as I suspected, the incompatibility goes deeper (probably because 4.0 is just too different from the 3.0 webkitgtk3 is expecting — right?):

    Preprocessing library webkitgtk3-0.14.1.0...
    In file included from ./hswebkit.h:37:

    #include <webkit/webkitversion.h>
             ^
    1 error generated.
    gtk2hsC2hs: Error during preprocessing

— does ths mean the webkitgtk version (2.10.4) in Homebrew is too new for this Cabal package?

[erikkaplun]

I checked and it seems webkitgtk-2.4.9 is the last ever version to contain any reference whatsoever to webkitversion.h — does this mean anything > 2.4.* is not suitable for cabal install webkitgtk3?

[erikkaplun]

There is now an open pull request for adding the webkitgtk-2.4.9 formula in homebrew/versions, if anyone is interested.

It compiles functionally equivalently to the MacPorts port it was based on.

https://github.com/Homebrew/homebrew-versions/pull/1077

I would also love it if anyone more deeply involved with how webkitgtk works, to take a look at the formula and perhaps offer some constructive criticism in the form of GitHub commit review, or even new commits!

Also, regarding #7 — if someone could offer some insight into how to migrate the webkitgtk3 Cabal package to webkitgtk-2.10.4 (or anything newer than 2.4.9), I'd be very curious.

[rodneyrod]

Getting this issue in Arch Linux too, is there any workaround to this?
